Where can I find my Authentication Key?
The Authentication Key is a code that enables access to our API. The Authentication Key looks similar to: df4385c2-33de-e423-4134-ca1f7b3ea8b7.
To find your unique Authentication Key, please log in to your DeepL Account.
The Authentication Key for CAT tools is included in the DeepL Pro Advanced and DeepL Pro Ultimate subscription plans. This gives you the possibility to integrate DeepL's translation technology in computer-assisted translation (CAT) tools, such as Trados Studio, memoQ, Déjà Vu, etc.
The Authentication Key for DeepL's API is included in a DeepL API Free or Pro plan. This allows you to integrate DeepL’s translation technology in your own products and services, as well as in plug-ins other than CAT tools.
If you are not sure which subscription you need for the integration, contact your third-party plug-in provider.
Please note that a subscription to DeepL Pro Starter is intended only for the translation of texts and documents using DeepL Translator and therefore does not provide you with an Authentication Key.
If you can't find an Authentication Key in your DeepL Account, please check whether you are subscribed to the right subscription plan.
